jon: a brand new look at one of the most secretive and controversial policies of the obama administration. good morning, i'm jon scott. jenna: hi, everybody. glad you're with us today. i'm jenna lee. these reports are surfacing of a confidential justice department memo that authorizes the killing of american citizens overseas in drone strikes. now there's a caveat. the killing is allowed if they're leaders of al qaeda or a associated terror group. this alone considered an imminent threat, even if there is it no clear evidence that a specific attack on the united states will take place in the immediate future. and the whole controversial issue sure to come up when the president's pick to head the cia john brennan, testifies at his confirmation hearings later this week. timing matters. chief intelligence correspondent herridge shirge is live in washington with more on this. >> reporter: this is clash between executive powers and congressional oversight. at center of this is the assertion by the obama white house it has the right to target american citizens for death without judicial review.
